In this section Husserl compares the progressive perceptual process of an immanent object with that of a transcendent (i.e. spatial object)‚ with special interest towards the Now phase of perception. He quickly points out that immanent objects only have ". . . one possible way to be given in the original in every Now . . ." which means during the duration of an experience of an immanent object‚ a color for example‚ the object is completely determined and the distinction between appearing and what

Synthesis Essay: Locavores Being a locavore seems to be becoming a trend among those who seek to protect the planet and its environment. These people claim that becoming a locavore is better‚ safer and more affordable for everyone. Recruiting people to become a locavore or to get involve in the locavore movement is the main goal of the locavore communities. They want to get as many people involve in order for their goals to be achieved. They give out certain tips and recommendations that truly

Synthesis Paper for Langston Hughes Introduction: Love is often regarded as an emotion that invokes extreme joy‚ hope and excitement. For example‚ Romeo and Juliet were a young couple who were so excited and hopeful about their love that they were willing to do anything to be together. However‚ there is another side to the feeling we call love that isn’t so joyous. The other‚ darker side of love is expressed by three Langston Hughes poem which show us the heart-break‚ the abandonment and the desperation

Nikki Vietz Ms Bontekoe Honors English 11 3 October 2013 Synthesis Essay By changing the word “nigger” to “slave” defeats the purpose of the Adventures of Huckleberry Finn being a historical piece of literature. Such a change means ignoring the past and the word “nigger” is part of that past. “Nigger” is demeaning and insulting but is its replacement any less demeaning and insulting. Changing the word would not only destroy the message that Mark Twain was trying to convey‚ but also America’s history

EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase

Prelab 5B Macrocyclic Synthesis OBJECTIVE: The objective this week is to produce Tetraphenylporphyrin and its metal complex. This will be carried out by condensation of 4 equivalents of Benzaldehyde and pyyrole in the presence of propanoic acid. The product will undergo UV/Visible Spectrum tests to determine its lambda max. The lambda max will show us the relationship between a conjugated system and the visible spectrum. PROCEDURE: Step 1: preparation of meso-tetraphenylporphyrin (TPP)
